A heat-insulating and wear-resistant lining board for coke-quenching car doors

Abstract

The invention discloses a special heat-insulated and wear-resistant lining plate for a coke quenching car door. The heat-insulated and wear-resistant lining plate comprises a shell, a fixing base, a connecting section, a support frame and a thermal insulating layer, wherein the shell is an outer cover; the fixing base is fixedly arranged inside the shell; the connecting part is arranged on the shell through the fixing base; the support frame is arranged inside the shell; and the thermal insulating layer is combined with the support frame, and filled into the internal enclosed space of the shell. The connecting section is connected with the coke quenching car door, and is arranged on the shell through the fixing base, so that the coke quenching car door can be effectively subjected to thermal insulation, and the shell is relatively wear-resistant. Therefore, the heat-insulated and wear-resistant lining plate has wear-resisting and heat-insulating properties, and the coke quenching car door can be effectively protected.

Description

technical field [0001] The invention relates to a coke quenching car, in particular to the heat insulation and wear-resistant structure of the coke quenching car door. Background technique [0002] The coke quenching car is an important equipment in the coking process, which is used to receive the coke pushed out from the carbonization chamber, and transport the coke to the bottom of the coke quenching tower and unload it on the coke cooling platform. The coking car is composed of a frame supported on two groups of railway double-axle trolleys and a carriage fixed on the frame with three vertical wall panels and one inclined wall panel. The vertical siding is made of hedges (so that water can flow away quickly when the coke is quenched); the inclined siding is paved with detachable steel plates, and the coke that has been extinguished falls along the cast iron plate to the cool on stage. [0003] Coke is unloaded from the carriage through coke discharge doors pivotally mou...

AI Technical Summary

Problems solved by technology

[0005] The liner is generally made of cast iron. During use, it is subject to rapid heating and sudden cooling in a short period of time, which is easy to cause rupture and damage; cast iron or steel has high thermal conductivity, and the hot coke will transfer heat to the frame steel structure in a short time In general, the local temperature of the frame steel structure rises, the strength of the material decreases a lot at high temperature, and the structure undergoes large deformation and damage.

As a result, the coke quenching car will be overhauled or replaced within 3-4 months
