Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described:

[0017] Such as figure 1 , 2 Shown, a kind of method for plugging dummy head, this method comprises the following steps successively:

[0018] 1) Use a paper rope to block the gap between the dummy head and the crystallizer;

[0019] 2) Lay a layer of heat insulation cloth on the bottom of the dovetail groove of the dummy head;

[0020] 3) Insert a section of rail head at the center of the dovetail groove body;

[0021] 4) Evenly spread a layer of iron filings on the surface of the dummy head including the inside of the dovetail groove;

[0022] 5) Thin flat steel about 200mm long is evenly arranged radially around the rail head.

[0023] The thermal insulation cloth described in step 2) of the above-mentioned method is to facilitate the separation of the dummy head when taking off the dummy ingot.

[0024] The rail head described in the above method step 3) can be cu...

Abstract

The invention discloses a method for blocking a dummy bar head; the method mainly adopts a rail head and a cold burden to block the dummy bar head according to the shape of a dovetail groove on the dummy bar head. The method has the advantages that the requirements for an operator are lower, the method is easy to be mastered and can solve the problems of casting failure caused by nonproficiency of operators or minor failure of equipment. By adopting the method, except for the casting failure caused by objective reasons resulting from liquid steel components and temperature, the method can not cause casting failure in other cases, can especially overcome the abnormal phenomenon such as untight closing of a stopper and the like and ensure successful casting. The method can effectively ensure the smooth overall continuous casting production, increase the operating rate of a casting machine and reduce production cost.

Description

technical field [0001] The invention relates to a continuous casting production technology, in particular to a method for blocking dummy heads. Background technique [0002] Before presenting the present invention, those skilled in the art and operators knew very well that plugging dummy head is a key operation step in continuous casting production. Steel and other production accidents. At present, there are many ways to block the dummy head on the billet, for example: iron castings with rigid dummy rods, cold baskets with flexible dummy rods, cold blocks with flexible dummy rods, etc. For flexible dummy rods, the two methods of cold basket with flexible dummy rod and cold material block with flexible dummy rod have higher requirements for operators, and the seedling time must be strictly controlled, and the stopper rod operating mechanism, There must be no faults in the vibrating equipment, otherwise, the pouring will fail due to insufficient seedling time, or the nozzle ...
