Description

A spreader and hoisting equipment for heat treatment of blank rolls

technical field

The utility model belongs to the technical field of heat treatment tooling, in particular to a hanger and a hoisting device for heat treatment of a blank roll.

Background technique

During the processing of the work roll, it is a very important process to heat treat the blank form of the work roll, that is, the blank roll. In the traditional heat treatment process of the blank roll, the blank roll is usually placed horizontally into the resistance furnace for heating, but When heat treatment of the blank roll is carried out in this way, due to the relatively large length and weight of many blank rolls, the middle of the blank roll will sink and deform, which increases the difficulty of subsequent processing of the blank roll, and even produces waste products. The method of placing the blank roll vertically in a pit-type resistance furnace avoids the problems mentioned above.

However, when the blank rolls are placed horizontally, the hoist can only lift one blank roll into the resistance furnace at a time, so the production efficiency is low, and the vertical placement method can put multiple blank rolls at the same time for heating, but horizontally. The hoisting tool for hoisting the blank rolls is not suitable for the vertical hoisting of the blank rolls, and cannot hoist multiple blank rolls at the same time, so the efficiency is relatively low. When the blank roll is vertically hoisted, due to the large size and weight of the work roll, it is not easy to hoist, and multiple work rolls are hoisted at one time, which increases the difficulty of hoisting, and the existing shaft parts spreader cannot meet the mass production. Therefore, a special vertical hoisting sling for heat treatment of blank rolls is required. Due to the high temperature and harsh environment during the heat treatment process, the wear of the spreader will increase, which will easily lead to safety accidents. However, every time a new spreader must be replaced, it will increase the cost of the enterprise. Therefore, considering the interchangeability of the spreader parts is also a problem. issues that need to be considered.

Since the blank roller is a shaft part, when heat treatment is carried out in a vertical way, not only the problem of the hanger used, but also the problem of how to hang the blank roller on the hanger must be considered. The complete set of equipment for vertical hoisting of the rolls for heat treatment cannot efficiently and safely hoist the blank rolls, so it is very necessary to improve the hoisting equipment during the heat treatment of the blank rolls.
