Roller bed preparation method for preventing pellets from being pressed in steel plate in shot blasting room

Abstract

The invention discloses a roller bed preparation method for preventing pellets from being pressed in a steel plate in a shot blasting room. The roller bed preparation method comprises the following steps: tempering 45# steel to manufacture a base metal (1), and processing the base metal to a designed dimension, wherein the thickness of the tempered base metal (1) is HB220-260; then surface-overlaying an overlaying layer (2), the unilateral thickness of which is 10 mm and the hardness HRC of which is greater than or equal to 45, to the base metal (1) by employing a wear-resistant welding stickand carrying out certain correction and surface processing on an overlaid roller; and finally, after an exterior mold is manufactured, pouring rubber directly out of the overlaying layer (2) to manufacture a rubber layer (3). The roller bed preparation method has the advantages that pellets can be prevented from being pressed in the steel plate better, damage caused by wear of the roller bed by the pellets is avoided, and the quality of the steel plate and normal operation of production are guaranteed.

Description

technical field [0001] The invention relates to the technical field of shot blasting machine roller table, in particular to a method for preparing a roller table used in a shot blasting chamber to prevent pellets from being pressed into a steel plate. Background technique [0002] The shot blasting machine is used to blast the upper and lower surfaces of the steel plate at the same time to remove the iron oxide scale of the steel plate, so as to meet the requirements of the steel plate entering the heat treatment furnace or surface painting. [0003] Normally, the upper and lower parts of the shot blasting machine are respectively equipped with four throwing heads, each of which is driven by a 37KW motor, and the throwing speed is about 90m / s. The shot hits the upper and lower surfaces of the steel plate, which can remove the oxide scale on the steel plate. The steel shot models are S330 and S460. The mixed size of the steel shot is 1~1.5mm, and the hardness is 43~50 HRC; th...
