1. Billet Grinding Machine Application:
This square billet grinding machine mainly repairs the defects such as cracks on the surface of the slab and the oxide layer, or repairs the surface to improve the surface quality of the slab. This billet grinding machine can complete the full stripping, angle grinding and local repairing of the billet surface, which is the guarantee of the next process, thereby improving the surface quality of the billet and improving the economic benefits of the enterprise.
This billet grinding machine is controlled by PLC to realize the functions of full-automatic peeling and grinding of the steel surface and manual control point grinding. The operation is simple and the maintenance is convenient.

1. The above billet grinding machines are suitable for the grinding of square billets, rectangular billets, forgings, round billets and steel ingots of different specifications. The entire unit is designed and manufactured in accordance with the actual requirements of the user. It has the advantages of high automation, high grinding efficiency, and convenient maintenance.
2. The data in the table are the completed project parameters of our company. Our company can make the optimal design according to the requirements of the customer and the specific conditions of the project;
The main features of the billet grinding machine are as follows:
The billet grinding machine is heavy metallurgical equipment with high strength and durability. The equipment uses a high-power grinding head with high efficiency.
The grinding head pressure is controlled by the proportional valve, and the change of grinding head pressure can be controlled at the same time when the trolley speed changes, so floating grinding can be achieved.
The billet grinding machine has multiple safety protection devices and an optimized layout, which not only protects the safety of personnel but also facilitates the operation of personnel.
The square billet grinding machine is a kind of equipment used to grind stone and steel. Its advanced nature is mainly reflected in the following aspects:
1. The square billet grinding machine integrates light, point, machine, and hydraulic control. It adopts PLC and servo constant power control technology to meet the production needs of different products.
2. Constant pressure and constant pressure constant power load control device under the pressure of the grinding wheel of the billet grinder, so that the set cutting depth of the billet does not change during the grinding process because the diameter of the grinding wheel gradually becomes smaller.
3. The square billet grinding machine's hydraulic control system can automatically adjust the grinding wheel's grinding pressure to avoid the loss caused by too deep grinding when the table at both ends of the billet is decelerated and reversed.
4. The square billet grinding machine can control the surface defects of the billet, position memory, the determination of the grinding wheel position coordinates and the grinding time are controlled by the computer so that it can perform local automatic grinding.
