Preferably, be evenly distributed with three baking holes at the top of described casing, described baking hole be shaped as circle or ellipse, described baking hole is equilateral triangle and distributes.
Preferably, described supporter is I-steel or steel plate.
Preferably, be welded with shoulder guard at described supporter, the thickness range of shoulder guard: 6-10mm.
Preferably, be provided with chamfering in the bight of described casing.
Preferably, the diameter range of described blast pipe is: 60-100mm.
Preferably, be provided with three hooks at the top of described casing, one of them hook is arranged on the center line at described casing top, and other two hooks are symmetricly set on the both sides of the center line at described casing top.The purpose that is symmetrical arranged three hooks is: the casing top is horizontal constantly when guaranteeing lifting.
Preferably, described shoulder guard top edge is lower than casing top edge 50-100mm, and the shoulder guard lower limb is higher than casing lower limb 100-200mm.
Preferably, the inboard of described shoulder guard is welded with reinforcing bar, and described reinforcing bar is provided with asbestos layer.
The beneficial effects of the utility model are:
1. the utility model increases support, adopts double-decker at the inwall of described casing, and uses asbestos layer to protect at the baking position, avoids localized hyperthermia.
2. the utility model changes steam vent into blast pipe, and the bottom of its blast pipe is goed deep into casing and reached degree of depth 1/3-1/2 place, is conducive to high-temperature gas at position formation circulation up and down, even internal temperature.
3. the inner steel plate of double-decker of the present utility model does not all seal up and down, is conducive to inside and outside gas and forms circulation, improves the side temperature homogeneity.
4. the utility model reasonable Arrangement baking hole avoids local baking overheated.
5. sidewall of the present utility model adopts suitable angle, and across corner is polished formation chamfering, minimizing side and bight resistance.
6. three hooks of welded top of the present utility model, the upper surface of the anti-material cast of tundish servicing unit is horizontal when guaranteeing lifting, and when having avoided the proposition servicing unit, unbalance stress damages the anti-material of bag wall.
In sum, by the improvement to the anti-material cast of tundish servicing unit, the cabinet wall problem on deformation of the anti-material cast of described tundish servicing unit alleviates greatly, by soldering in original about two months once bring up to about 9 months soldering once service life, stopped because of the inhomogeneous top of the baking temperature material problem of collapsing, the easy particle problem in bight is effectively controlled, once propose success rate after baking finishes and reach more than 95%, improved operating efficiency, produced favorable economic benefit.
