After years of technical accumulation, the expert team has innovated and mastered the key core production technology and implemented its industrialization, which is to break the monopoly of the industry and make efforts for the dream of making China into a powerful country.The company's products are: rock drill rig, open pit drill, rock drill, hydraulic rock drill dedicated MF rod drill, common thread drill, drill tail, drill head and other ancillary products.
1.Steel smelting and rolling
Steel smelting quality control, rolling quality control and later product deep processing are equally important. HZJX adopts the production process of refining + vacuum + continuous casting + drilling + surface peeling at the production site of Shanghai Baosteel Group. The key points of strict quality control include but are not limited to:
·The content of non-metallic inclusions A, B, C, D≤0.5
·Remains of harmful elements Pb, Sn, Sb, As, etc. ≤0.01%
·Gas content O≤10ppm, H≤2ppm rolling surface decarburization≤0.05mm
2.Thread Designing and Manufactuning
Scientific and standard thread tooth profile design is the basis for high-quality threaded connections of drill products, and production that strictly adheres to thread dimensional accuracy is the only way to ensure excellent threaded connection performance. Inaccurate thread connection, too large or too small matching clearance, will cause high-frequency vibration and shaking of the thread part of the drill tool during the rock drilling process, resulting in local working high temperature, which will cause the thread part to break.
3.Heat treatment: Overall carburizing + Air cooling quenching + Tempering
Overall carburizing+ air-cooled quenching + tempering process keeps the product high in toughness, and air-cooled quenching greatly improves its surface hardness and overall strength indicators.
·Heat treatment deformation ≤ 2%
In order to obtain a higher service life and effect of the thread, the thread part is strengthened specifically to improve its strength and wear resistance.
The industrialization demonstration project of Guizhou University is a concrete practice of applying the basic principle of anti-fatigue manufacturing to heavy hydraulic drill rod.
The company produces and sells high-end heavy hydraulic drill rod, drill tail, drill head, connecting sleeve, as well as Atlas, Montebay, , Guhe and other drill accessories.
It is our goal to reduce the production cost of enterprises and improve the competitiveness of customers' products. Our company is also willing to form a strategic partner with domestic oems and OEM end-users to jointly face the environment and big market and contribute our strength to the rapidly developing Chinese machinery industry.
The company has established a war with two scientific research institutions of Guizhou University, "National and Local Joint Engineering Laboratory of High Energy Metal Structure Materials and Manufacturing Technology" and "Guizhou Key Laboratory of Material Structure and Strength"
Road cooperation, the establishment of China - made basic components of the disease-resistant labor manufacturing base.
