Sink rolls surfacing support device and design of resistance furnace
In the surfacing process of sink rolls, a support device is used, which includes a base, the middle part of which is provided with a groove, the base is provided with a bracket, the base plate of the bracket is fixed on the groove of the base, and the upper part of the bracket is There is an installation shaft, and the installation shaft is provided with a support wheel for supporting the sink rolls.
The base of the sink rolls surfacing equipment is provided with a through hole, the through hole is parallel to the groove in the middle of the base, a screw is arranged in the through hole, a screw is arranged in the middle of the bottom plate of the bracket, and the screw is There are screws, and the left and right ends of the base are provided with cylinders for adjusting the height of the sink rolls.
The results show that the roller surfacing support device has the advantages of simple structure, reasonable design, and convenient adjustment of the relative position of the support wheel and the sink rolls.
In addition to the support device, the special resistance furnace for large-scale roll weld repair heat treatment is also very important. The length of the cavity in the heating area of the resistance furnace is slightly larger than the length of the sink rolls, and the height of the cavity in the heating area is slightly larger than the sum of the diameter of the roll body and the height of the carrier car.
The furnace door of the resistance furnace is set on the additional furnace door carriage. There is a through hole in the middle of the furnace door, and the diameter of the through hole is slightly larger than the diameter of the roll neck. There is also a furnace door temperature insulation area on the furnace door compartment. Outside the door, the diameter of the furnace door temperature insulation area is the same as the diameter of the furnace door through hole, and the furnace door temperature insulation area of the roller surfacing machine is sealed and fixed with the furnace door.
There is also a through hole in the back wall of the resistance furnace. The diameter of the through hole in the back wall of the furnace is slightly larger than the diameter of the roll head of the roll. The diameter of the heat preservation area behind the furnace is the same as the diameter of the through hole on the back wall of the furnace, and the heat preservation area behind the furnace is sealed and fixed to the back wall of the furnace.
