Device and method for different steel grade continuous casting automatic iron plate insertion

Abstract

The invention discloses a device for different steel grade continuous casting automatic iron plate insertion, and belongs to the technical field of metallurgy continuous casting. The device comprises a T-shaped base of a tundish, a nozzle quick-changing oil cylinder swing part, a movable swing part and an iron plate insertion body part. The invention also discloses a method for different steel grade continuous casting automatic iron plate insertion, which comprises the steps of during different steel grade continuous casting, inserting the movable swing part on the T-shaped base of the tundish so as to enable the movable swing part to be located at the middle of the bottom of the tundish, meanwhile putting down a swing rod of the nozzle quick-changing oil cylinder swing part, respectively connecting two long rods of the iron plate insertion body part into hollow swing rods at the lower parts of the nozzle quick-changing oil cylinder swing part and the movable swing part from the inner arc side of a crystallizer, and connecting firmly by using iron wires. By adopting the device and the method, the different steel grade same-tundish continuous casting iron plate insertion automation is realized, the continuous casting furnace number of a casting machine is increased, the cost of tundish refractories is reduced, the operability of the casting machine is indirectly improved, the production preparation time is saved, and the molten steel yield is also improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, and in particular relates to a device and method for continuous casting of different steel types and continuous pouring and automatic insertion of iron plates. Background technique [0002] Continuous casting of steel grades between different grades is an important way to increase the number of continuous casting furnaces, and it is also one of the important means to reduce the cost of refractory materials in the continuous casting process. With the development of the iron and steel industry, the competition is becoming more and more fierce, and the composition and difference between the steel grades are getting larger and larger. The situation of continuous casting of steel grades between different compositions has appeared. The two pieces of each stream gradually increased to four pieces, and when the steel grades between the non-crossing components were poured continuo...

Problems solved by technology

With the development of the iron and steel industry, the competition is becoming more and more fierce, and the composition and difference between the steel grades are getting larger and larger. The situation of continuous casting of steel grades between different compositions has appeared. The two pieces of each stream gradually increased to four pieces, and when the steel grades between the non-crossing components were poured continuously, the resulting mixed billet even reached 5 pieces per flow, which had a particularly serious impact on the composition of the previous furnace, which was invisible Among them, the problem of carrying out products in the contract has been added. At the same time, with the increase of the particularity of customer needs, this problem has become increasingly prominent. In order to reduce the continuous casting of steel types between different components, the problem of increasing the number of mixed casting billets
