Open-hearth furnace riding wheel running-in device

Abstract

The invention discloses an open-hearth furnace riding wheel running-in device which comprises a rack (1). A horizontal oil cylinder (2), a high-temperature cabin (3), a support (81) and a laser velocimeter (9) are arranged on the rack (1), an upper fixing frame (41) and a lower fixing frame (42) are arranged in the high-temperature cabin (3), and a supporting frame assembly is arranged between thetwo fixing frames; a guide lubricating assembly is arranged on one side of the high-temperature cabin (3), an air heating pipe (7) is arranged on the other side of the high-temperature cabin (3), anda thermocouple (35) is arranged on the high-temperature cabin (3); a pressing head (43) is arranged on the upper fixing frame (41), and a vertical oil cylinder (8) is arranged above the pressing head(43). The high-temperature cabin is arranged to guarantee the running-in temperature, the vertical oil cylinder and the supporting frame assembly are arranged to extrude a riding wheel fixed to the fixing frame, the pressure requirement of running-in is guaranteed, the laser velocimeter is used for judging the running-in degree, the structure is simple and compact, and the operation is convenientand fast.

Description

technical field [0001] The invention relates to the field of boiler chain row support wheel manufacture, in particular to a running-in device for an open hearth furnace support wheel. Background technique [0002] At present, the hearth of the open hearth furnace is equipped with a chain row for ash discharge, and the chain row is driven by a supporting wheel. Under long-term high temperature, the supporting wheel has a long service life and needs to be replaced, and the newly replaced supporting wheel is due to the internal transmission part. There is a fit error in the installation process itself, coupled with the high temperature, there is a deviation in the movement consistency between the new supporting wheel and the old supporting wheel, and the transmission running-in effect of the new supporting wheel is not good, so that the wear and tear of the later use is relatively large; If all supporting rollers are replaced at one time, the cost is too high, and there is also...

[0002] At present, the hearth of the open hearth furnace is equipped with a chain row for ash discharge, and the chain row is driven by a supporting wheel. Under long-term high temperature, the supporting wheel has a long service life and needs to be replaced, and the newly replaced supporting wheel is due to the internal transmission part. There is a fit error in the installation process itself, coupled with the high temperature, there is a deviation in the movement consistency between the new supporting wheel and the old supporting wheel, and the transmission running-in effect of the new supporting wheel is not good, so that the wear and tear of the later use is relatively large; If all supporting rollers are replaced at one time, the cost is too high, and there is also the problem of inconsistent running-in, which affects the ash output effect and service life of the open hearth furnace
