Abstract
The invention provides a multilayer stopper rod for continuous casting, which comprises a stopper rod body and a stopper rod head, wherein the stopper rod head at least comprises one lining layer, and an external surface of the lining layer and an external surface of the stopper rod body are smoothly transited. In the provided multilayer stopper rod, since different materials can be selected and used at different parts of the lining layers according to requirements, the washing for the stopper rod head is reduced, and the better erosion resistance is displayed, and further, the service life of the stopper rod is prolonged, the pollution to liquid steel can be reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of continuous casting multilayer stopper.
Background technology
Continuous casting is the important production process of modern steel metallurgy, and stopper is continuous casting one of functional refractory, is the critical elements of control continuous casting tundish to the molten steel flow and the mold liquid level height of continuous cast mold.
This just requires stopper that good anti-molten steel aggressivity, thermal shock resistance and high rupture strength are arranged, continuous casting stopper rod in use, and the head of general common stopper adopts single batch mixing to make, as shown in Figure 1, stopper is deteriorated seriously owing to being subjected to washing away more greatly by Stopper Body 11 and caput 1, thereby influences the service life of stopper.Simultaneously.Because caput washes away to deteriorate and seriously causes the uncontrollable molten steel flow speed of stopper, has a strong impact on the whole efficiency of continuous casting.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of continuous casting multilayer stopper is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of continuous casting multilayer stopper comprises Stopper Body and stopper head, and wherein said stopper head includes one deck backing layer at least, described backing layer outer surface and the transition of described Stopper Body outer surface smoother.
Beneficial effect of the present invention is mainly reflected in: continuous casting can be selected the backing layer of different materials as required at different positions with the multilayer stopper, minimizing is washed away the stopper head, can better corrosion resistance, thus service life of stopper prolonged, enhance productivity.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: stopper generalized section of the prior art.
Fig. 2: continuous casting of the present invention multilayer stopper generalized section.
Wherein:
1 caput, 11 Stopper Bodies, 2 stopper heads
21 backing layers
The specific embodiment
The present invention has disclosed a kind of continuous casting multilayer stopper, as shown in Figure 2, comprises Stopper Body 11 and stopper head 2, and wherein said stopper head 2 includes one deck backing layer 21 at least, described backing layer 21 outer surfaces and the 11 outer surface smoother transition of described Stopper Body.
The present invention compared with prior art has the following advantages: the kind of the molten steel that continuous casting can be cast as required with the multilayer stopper, select different materials at different positions, the backing layer of different-thickness can reduce washing away the stopper head, has better corrosion resistance, thereby prolong the service life of stopper, enhance productivity, and can reduce pollution molten steel.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
Claims (2)
