Continuous casting slabs or primary rolling slabs are used as raw materials, heated by a stepping furnace, and dephosphorized by high-pressure water, and then enter the roughing mill. The rough rolling material is cut through the head, tail, and then into the finishing mill, and computer-controlled rolling is carried out. After the final rolling, it will go through laminar cooling (computer-controlled cooling rate) and take-up by the coiler to become a straight hair coil. The head and tail of straight hair curls tend to be tongue-shaped and fish-tailed, with poor thickness and width accuracy, and often have wavy, folded, tower-shaped and other defects on the edges. The coil is heavier and the inner diameter of the steel coil is 760mm. (Generally used in the pipe-making industry.) After straightening the hair through the cutting head, tail cutting, trimming and multi-pass straightening and smoothing finishing lines, and then cutting or re-rolling, it becomes: hot rolling steel plates, flat hot rolled steel coils, slitting tapes and other products. If the hot-rolled finishing coil is pickled to remove scale and coated with oil, it will become a hot-rolled pickled coil.

The pump truck is suitable for the harsh geological conditions such as the plateau and the areas where the drilling equipment is inconvenient to handle. The pump truck can carry 800 kilograms of heavy objects, which can effectively reduce the labor intensity of workers and improve the working efficiency. This innovation has opened the track for mud-track crawlers in the drilling industry and filled the gaps in the industry.
The pump truck has fixed the improved NBB-250/6A mud pump on the crawler chassis, added hydraulic pump station, and driven the track by hydraulic motor. The hydraulic pump station shares a motor with the mud pump. The crawler and mud pump work through the clutch. By switching, the truck can be driven by the joystick on the car, which facilitates the relocation of the equipment at close range from the drilling operation in the plateau hilly terrain, and can effectively protect the surface vegetation from serious damage. It is a practical, convenient and environmentally friendly new model. Drilling equipment.
Stone coal machine successfully developed a new track walking mud pump truck
Recently, two new crawler-driven mud pump trucks independently developed by Shijiazhuang Coal Mine Machinery Co., Ltd. were transported to Shigatse of the Qinghai-Tibet Plateau and will be used for radioactive mineral exploration projects.
