Pre-warming device for steel plate pretreatment line

Abstract

The invention discloses a pre-warming device for a steel plate pretreatment line. The pre-warming device for the steel plate pretreatment line comprises a pre-warming chamber; the left side wall and the right side wall of the pre-warming chamber are provided a with heat-preserving layer; coil pipes located on the middle portion of the heat-preserving layer are further arranged on the left side wall and the right side wall of the pre-warming chamber, and are controlled by a control device to be capable of warming and heating the pre-warming chamber; four vertically arranged guide rails locatedon the four edge and corner portions of the pre-warming chamber are in the pre-warming chamber, and are provided with a steel plate installing base capable of vertically rising and falling on the guide rails; and a movable trolley is arranged at the bottom of the pre-warming chamber, and can be used for outputting a pre-warmed steel plate. After the structure is adopted, the steel plate can be installed on the installing base to be placed into the pre-warming chamber to be pre-warmed and pre-heated, after certain temperature is achieved, the steel plate is output through the movable trolley and then is conveyed to a pre-heating chamber to be pre-heated, the pre-warmed steel plate can be fast pre-heated in this way, the pre-heating time is shortened, pre-heating indexes are achieved, the production cost is saved, and the subsequent shot blasting effect is guaranteed.

Description

technical field [0001] The invention relates to an auxiliary device for a steel plate pretreatment line, in particular to a preheating device for a steel plate pretreatment line. Background technique [0002] The steel plate needs to be preheated before shot blasting to remove surface water, increase the temperature of the steel and achieve the initial effect of oxidation and shedding, so that the rust on the surface of the steel plate can be better removed in the subsequent shot blasting treatment. The existing technology In the shot blasting chamber, a preheating chamber is usually installed in front of the shot blasting chamber, and the preheating chamber is directly used for preheating. The traditional method can contact the steel surface through the burning flame flow, carbonize the surface oil, remove surface water, and improve Steel temperature, but because the preheating temperature does not reach the target, the preheating effect is not good, which affects the subse...

Problems solved by technology

[0002] The steel plate needs to be preheated before shot blasting to remove surface water, increase the temperature of the steel and achieve the initial effect of oxidation and shedding, so that the rust on the surface of the steel plate can be better removed in the subsequent shot blasting treatment. The existing technology In the shot blasting chamber, a preheating chamber is usually installed in front of the shot blasting chamber, and the preheating chamber is directly used for preheating. The traditional method can contact the steel surface through the burning flame flow, carbonize the surface oil, remove surface water, and improve Steel temperature, but because the preheating temperature does not reach the target, the preheating effect is not good, which affects the subsequent shot blasting treatment. If you want to prolong the preheating time, you have to delay the process of the whole set of equipment, resulting in a waste of production costs
