HFD Mining Equipment QL DTH Bit and Sandvik Benchmarking
First of all, let me explain that we are a mining equipment manufacturer from China, how did we get involved with Sandvik, a seemingly high profile and hardcore construction machinery company.
HFD started out as a diamond rope manufacturer, with no technical accumulation in mining equipment tools and a network to build from scratch.
The most dangerous thing is the change of rivals, before doing diamond cutting rope, the rivals are just some small domestic companies and "second-hand dealers", but Sweden's Sandvik is a big brand in the world. We hard scalp, simply ants challenge the elephant, dead will not have a sound issued.
R & D products at the initial stage, went to visit a material listed company's parent company, their family is to do tungsten carbide cobalt alloy is tungsten carbide cobalt alloy, at that time, the main body of our company's R & D personnel are basically mining research institute and the Central and South University of Technology, so you can develop a large-diameter, high-pressure wind down hole drilling tools.
Of course, you can't use ordinary metal to deal with hard rock, used for rock drilling tungsten carbide teeth inlaid on the drill bit, due to the product is more advanced than similar domestic products, due to the performance of domestic tungsten carbide teeth is not up to the standard, often appear in the construction of a certain degree, the teeth broken, the product rework problems. Although there were some detours on the alloy teeth, it didn't delay much time. We continuously looked for many domestic manufacturers supplying alloy teeth, and it so happened that in the previous cemented carbide company, there was a master's degree student who made extra coarse crystal mining carbide. Life relative to ordinary The specific principle: the performance and characteristics of tungsten carbide cobalt alloy depends on the grain size of tungsten carbide particles and cobalt powder content and distribution. For cutting tools, the grain size of tungsten carbide For cutting tools, tungsten carbide grain size should be as small as possible, and vice versa for mining alloys. At the same time, the cobalt used in the binder is also treated in a special way: after carburizing, the phase in the surface layer is eliminated and the Co migrates to the center, resulting in a low C0 content in the surface layer and a high C0 content in the center. This cobalt content gradient distribution of cemented carbide surface hardness, good wear resistance, the heart has a good impact toughness, alloy wear resistance and toughness has been well coordinated, the use of the effect of the traditional products have significantly improved a In other words, the higher the cobalt content, the softer the hardness, but the higher the toughness.
Equipped with the new alloy teeth, the one-time service life of the drilling tools did rise significantly, but encountered other problems: the quality of the domestic special steel is not satisfactory, the teeth did not break, but the panel on the drilling tools had problems leading to the teeth falling off, it seems that in order to catch up with the overseas leader, the relevant domestic products there is still quite a long way to go.
Subsequently, I gave up my dream of transforming into a primary market because of certain things, and this experience made me think that materials are really quite fun. Due to the shortage of materials, many urgently needed accessories, can not get into the goods, the company is very clear about the drilling tools industry R & D how much money, how high the cost of "high input, high output" is the only way, in the initial stage of the enterprise, the R & D staff have too much responsibility requirements will inevitably make their hands and feet, a strong spirit of adventure and tolerance for trial and error, a broad mindedness. A strong spirit of adventure and tolerance for trial and error is the source of the company's continuous growth.
Many of us have never been down a mine, but obviously we all know that the underground environment is not only very harsh, but also highly dangerous. Out of the importance of safe production, as well as to reduce mining costs and improve mining efficiency, more and more mines will be remote control trackless equipment, automated trackless equipment applied to the production of underground mines. More than 85% of mines in western industrialized countries use trackless equipment. And some of the world's advanced mines, such as Australia's North Parkes copper gold
North Parkes Mine, Finsch Mine in South Africa, Chelopech Mine in Bulgaria, Pihasalami Zinc Mine in Finland, and world-renowned mining contractors through the use of intelligent trackless equipment.
(Chelopech Mine) in Bulgaria, PYHASALMIMINE in Finland, as well as globally renowned mining contractors have made underground metal mining more and more transparent through the use of intelligent trackless equipment, advanced equipment management, and mine management software systems, which collect and analyze data in real time to manage mine operations.
Firstly, taking the frontline production environment as an example, the operator can see exactly how the vehicle is traveling through the on-board camera in the control room of the shaft. The operator can also control where and when the vehicle is traveling. In fact, it is the intelligent systems and various algorithms that perform all the tasks: following a set route, calculating speed, controlling the brakes, steering, loading, transporting and unloading, Underground Scrapers are of an articulated design HFD has developed a series of drills with high wind pressures, which have performed well in mining, e.g. QL DTH Bit
The company attaches great importance to talent, for excellent talent at any cost, once, the company in order to save a local market, the company's top management personally rushed to Harbin, when it is known that the customer to be in the hotel to negotiate with another drilling tool brand, just arrived in Harbin could not care about a mouthful of water, immediately rushed to the hotel lobby to wait for the customer because he did not know when the customer to talk about the end of the day, he has been guarding the place do not dare to leave, and even dare not eat! He didn't even dare to eat. Only to late at night 1:30, the customer finally came out, the other side of the sentence no time to go.
However, we did not stop there. We continue to recruit talented people, lead the team to conduct on-site testing in various mining areas, and constantly improve our products. Since joining the company in 2017, my sunburned skin symbolizes my persistence and hard work. Starting with raw materials, we use XGQ25 high-strength alloy steel. Despite the high cost, we have conducted many tests to ensure the durability of our products. Most of the income was invested in R&D. We always insisted on prioritizing quality and refused to reduce wages even in difficult times, so we can say that it was a back-breaking battle.
In 2013, HFD Drilling Tools participated in the conference for the first time, and put up the slogan "There is no savior, nor do we rely on the gods and emperors, we rely on ourselves to create a new life" on the booth. This spirit of hard work is deeply engraved in every company, once, has been a meter drilling team to Hebei Province is playing a well, drilling to a depth of 117 meters, according to the drilling team experience, a well can be completed in one day, with the drill bit to go deeper and deeper, bringing the soil is really very dry, a little sign of groundwater are not. At this time, the depth of the well has been more than 100 meters, it is reasonable to say that should be drilled to the water layer, why there is still no water that, soon through unremitting efforts to get the answer, followed by the people around the people also saw, immediately pointing in the direction of the drilling well and shouted "look, out of the water".
Figure work is easy, success is difficult; success is easy, keep work is difficult; keep work is easy, final work is difficult." Hard work many entrepreneurs can do, but to achieve the industry's first, still "paranoid" like to maintain hard work, and always ringing the alarm to remind the body to carry out the whole 30 years, such entrepreneurs can have a few?
