Abstract
The utility model relates to a cover plate for handle holes of a tundish cover. The cover plate is a simple device used for sealing the handle holes of the tundish cover in a continuous casting and tundish baking process. The cover plate is divided into two parts, namely a hoisting ring and a sealing plate; the sealing plate is in the shape of two Us spliced up and down. By using the simple device, tundish baking time can be greatly shortened, thereby achieving the aim of shortening the setup time; and at the same time, the cover plate reduces heat dissipation, and effectively saves gas using amount.
Description
Affiliated technical field
The utility model is in continuous casting tundish bake process, for saving gas using quantity, reduces the lost a kind of cover plate that places on the bag clad handle hole of heat.
Background technology
At present, the middle bag clad that continuous casting uses is except that the baking hole, and each beam all has a handle hole, is used to place under drainage sand, thermometric or the accident condition block up flow operation by handle hole with stifled eye awl.But in middle bag bake process, handle hole is in opening-wide state, and heat reaches the inclusion temperature consuming time length of production demand mainly from distributing here, and gas using quantity is big.With bag in 5 streams is example, and bag makes the bag wall temperature reach 85 ℃ in the baking, needs 5 hours, can not adapt to the rhythm of production of high efficiency continuous casting and the situation requirement of energy-saving and emission-reduction.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of simple mechanism---middle bag clad handle hole cover plate, and use this cover plate effectively to stop heat to distribute, save gas using quantity.
The technical scheme that its technical problem that solves the utility model adopts is: tundish clad handle hole is essential in casting process, in middle bag bake process its drawback is arranged but, can not satisfy energy-saving and emission-reduction and save the requirement of producing time.The utility model is designed the easy device that can effectively deal with problems according to the problems referred to above that exist in the bake process.This device divides two parts, and the first half is the suspension ring that nut is made, and suspension ring hook up the position for hand-held suspension hook, and the suspension ring shank diameter is not limit, and gets final product with the weight that sustains seal cover board.The latter half is a seal cover board, is mainly used in bag clad handle hole in the sealing, is shaped as two " U " word splice type up and down, suitably adjusts to be as the criterion can cover handle hole again.The about 20mm of thickness can be according to the actual conditions adjustment, deformation does not take place can tolerate baking burst apart and exceed.Firm welding is wanted in suspension ring and seal cover board junction.
The beneficial effects of the utility model are: saved gas using quantity, shortened the tundish stoving time greatly, the baking bag time foreshortened to 3.5 hours by original 5 hours, and this covering plate structure is simple, easily made, and was convenient to Maintenance and Repair.

Among Fig. 1: 1 suspension ring, 2 seal cover boards
Among Fig. 2: 1 suspension ring, 2 seal cover boards
Among Fig. 3: bag clad handle hole in the roasting mouth of 1 suspension ring, 2 seal cover boards, the 3 roasters 4 baking holes 5
The specific embodiment
In Fig. 1 and Fig. 2, suspension ring (1) note will with seal cover board (2) firm welding
In Fig. 3, during the online use of middle bag clad handle hole cover plate, only need before middle bag baking, hook suspension ring (1) with suspension hook and seal cover board (2) Gai Zaizhong bag clad handle hole (5) is gone up got final product.Bag clad handle hole cover plate can play sealing function in then in middle bag bake process, prevents that flame from therefrom routing up in the clad handle hole (5), reduces heat and distributes thereby reach, and saves coal gas, shortens the purpose of stoving time.
Claims (2)
1, a kind of middle bag clad handle hole cover plate is characterized in that shape is two " U " word splice type up and down, thick 20mm, and welded nut is made suspension ring.
2, tundish clad handle hole cover plate according to claim 1 is characterized in that top suspension ring for hooking up the position, and following seal cover board is used to seal tundish clad handle hole.
