Abstract

The invention relates to a stainless steel clad plate billet conticaster. It belongs to a continuous casting device in the art of metallurgical industry. The device can be characterized in that: it comprises three synchronous circulating mobile steel band crystallizers A, B and C, which are Y- type equipped, the lower cooling steel band 2 of crystallizer A being common with the right-side cooling steel 2c of the crystallizer C, and the lower cooling steel band 2b of crystallizer B being common with the left-side cooling steel 2d of the crystallizer C. After the strand being forged by from multigroup flexible guiders, multigroup steam- water spray devices and traction roller which are under the crystallizer C, the clad plate billet is aligned to horizontality by a blending guider and a smoothing roll, and then is sent to shearer to be sheared into a definite length or sent to continuous rolling mill to roll down. The merit is characterized in that: it improves the production efficiency of the conticaster, and guarantees the quality of strand and rolled metal.

Description

technical field

[0001] The invention relates to a stainless steel composite strip billet continuous casting machine, which belongs to near-net shape continuous casting equipment in the technical field of metallurgy industry. The continuous casting machine can not only continuously cast a single metal material thin slab strip, but also can continuously cast a composite slab strip of different metal materials, and is especially suitable for continuous casting of stainless steel composite slab strips. Background technique

[0002] The continuous casting machine is an important equipment in the continuous casting and continuous rolling process of the modern metallurgical industry. Its structural characteristics and working principle not only determine the working efficiency and production cost of the continuous casting machine, but also directly affect its product quality. The continuous casting machines used in the original continuous casting process are generally divided into ...

Embodiment Construction

[0041] 1. (See Figure 1) When producing stainless steel double-sided composite slab blanks, stainless steel water 15 is poured into crystallizer A through stainless steel water tundish 16 and stainless steel water casting tank 17; stainless steel water 15b is cast through stainless steel water tundish 16b and stainless steel water The tank 17b is injected into the crystallizer B, moves downward synchronously with the crystallizers A and B, and gradually cools and crystallizes into a stainless steel strip blank, and enters the crystallization together with the lower cooling steel strips 2 and 2b of the crystallizers A and B when cooled to an appropriate temperature At this time, the low-carbon molten steel 18 is injected into the gap reserved between the two stainless steel strip blanks of the crystallizer C through the low-carbon molten steel tundish 19 and the low-carbon molten steel casting tank 20. Device C continues to move downward synchronously. At this time, the inner si...
