Hydraulic walking-beam type round billet heating furnace cushion block and using method thereof

Abstract

The invention provides a hydraulic walking-beam type round billet heating furnace cushion block and a using method thereof and belongs to the technical field of a steel rolling heating furnace. The heating furnace cushion block comprises a first split type cushion block which is fixed on a walking beam and used for supporting a round billet and a second split type cushion block which is fixed on afixed beam and enables the round billet to roll and be positioned; when the heating furnace cushion block is in use, the overall heating process of the round billet is finished in the furnace in a stepping manner along with the direct circulation stepping actions of lifting, advancing, descending and retreating of the walking beam. The heating furnace cushion block has the beneficial effects as follows: the position of the round billet is fixed in the lifting and advancing processes of the walking beam, rolling and positioning of the round billet can be realized in the descending process of the walking beam, the overturn positioning is accurate, so that the heating area of round steel is increased, the condition of black patches during heating of billet steel is reduced, temperature uniformity of the round billet during heating is improved, and further, manufacturing cost and mounting difficulty of the cushion block are reduced.

Description

technical field [0001] The invention relates to the technical field of steel rolling heating furnaces, in particular to a cushion block of a hydraulic walking beam type round billet heating furnace and a method for using the same. Background technique [0002] When rolling continuous casting round billets to produce hot-rolled products, the heating furnace is generally a walking beam heating furnace, and the water beam is the key part of the walking heating furnace project. Usually, pads and pads are set on the water beam. Generally, it is made of materials with good heat resistance. The main function of the block is to reduce the shielding effect of the water beam, increase the heating surface of the billet, and reduce the cooling effect of the water beam on the billet. [0003] For the current round billet walking beam type heating furnace, the round billet frame is generally fixed on the pad when stepping, and the overall pad is provided with arc-shaped slots or saddle-sh...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a hydraulic walking beam type round billet heating furnace block and its use method, which solves the problems of black marks and uneven heating in the existing walking beam type heating furnace when heating round billets problem and to further solve the problem of high manufacturing cost, by setting the corresponding split pads on the walking beam and the fixed beam respectively, it not only increases the heating area of ​​the round steel, reduces the manufacturing cost of the pad, but also makes the round steel can be Rolling on the fixed beam reduces the occurrence of black marks when the billet is heated, improves the temperature uniformity of the billet during heating, and improves the heating quality of the billet
