Abstract
The utility model discloses a tundish ventilation water gap installing locating guiding plate in the field of steel making auxiliary devices. The tundish ventilation water gap installing locating guiding plate solves the problem of molten steel leakage caused by large peripheral seam filling joints caused by the fact that the existing tundish ventilation water gap is incorrect in installing and locating. The tundish ventilation water gap installing locating guiding plate is composed of a guiding column and a tray. The guiding column is formed by connecting an upper conical section and a lower cylindrical section smoothly. A gap between the periphery of the cylindrical section of the guiding column and the inner wall of the tundish ventilation water gap is 3-8 mm, the bottom of the guiding column is fixed on the tray vertically, and an annular groove for locating the tundish ventilation water gap pipe wall is formed in the tray and surrounds the bottom of the guiding column. By means of the guiding column of conical transition, natural and correct locating of the tundish ventilation water gap is ensured, the tundish ventilation water gap is located accurately, installing of the tundish ventilation water gap is smooth and free of seams, and molten steel leakage is prevented.
Description
Technical field
The utility model relates to a kind of middle bag gas-permeable nozzle of making steel the auxiliary equipment field positioning guiding plate is installed.
Background technology
Middle bag gas-permeable nozzle is the key component of steel circulation road, on connect middle back stall brick, under connect slide plate, have many gaps, in case combination seal is bad, heavy molten steel passes from gap, causes middle bag bleed-out; Gently form air gap, cause air directly to contact molten steel, cause serious secondary oxidation, significantly reduce steel quality.So the installation quality of middle bag gas-permeable nozzle is extremely important.
In installation process, all below middle bag gas-permeable nozzle, place a square plate in the past, middle bag gas-permeable nozzle is placed on to flat board from top to bottom upper, re-use stamp mass and fill up its gap location on every side.Such mounting means by experience range estimation location, easily forms the gas-permeable nozzle injustice fully, Disalignment, and the larger defective mounting that waits of seam, cause middle bag gas-permeable nozzle and slide plate, brick cup gap large, easily oozes steel or air-breathing.
Summary of the invention
The purpose of this utility model is to overcome the prior art defect, provides a kind of middle bag gas-permeable nozzle that positioning guiding plate is installed.
The technical solution of the utility model is achieved in that a kind of middle bag gas-permeable nozzle installation positioning guiding plate, it is, it is comprised of lead and pallet, and lead is formed by the conical section on top and the cylindrical section smooth connection of bottom, and the lead bottom vertical is fixed on pallet.
Bag gas-permeable nozzle tube wall in location preferably, is arranged around the lead bottom on pallet cannelure.
Preferably, lead cylindrical section periphery is 3-8mm with middle bag gas-permeable nozzle inwall gap.
The utility model, by the lead of tapering transition, has been guaranteed the naturally accurate dropping place of middle bag gas-permeable nozzle, has accurately located middle bag gas-permeable nozzle position, has guaranteed that the installation of middle bag gas-permeable nozzle is smooth seamless, has avoided molten steel to ooze out.
The accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model top view.
In figure, 1-lead; 2-cylindrical section; 3-conical section; 4-pallet; 5-cannelure.
The specific embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1 and Figure 2, a kind of middle bag gas-permeable nozzle is installed positioning guiding plate, by lead 1 and pallet 4, formed, lead 1 is formed by the conical section 3 on top and cylindrical section 2 smooth connections of bottom, cylindrical section 2 peripheries of lead 1 are 5mm with middle bag gas-permeable nozzle inwall gap, so that accurate bag gas-permeable nozzle position in the location, lead 1 bottom vertical is welded on pallet 4, on pallet 4, around lead 1 bottom, location is arranged in the cannelure 5 of bag gas-permeable nozzle tube wall.
During work, with lift cart, hold the utility model, place it in middle bag gas-permeable nozzle installing hole below, middle bag gas-permeable nozzle is down placed from the brick cup hole, and it is downward that tube wall is enclosed within on lead 1 conical section 3 along lead 1, until pallet 4 is caught middle bag gas-permeable nozzle, and middle bag gas-permeable nozzle tube wall sticks into cannelure 5 location, then lift cart is upwards held out against, can't become flexible to this positioning guiding plate, location, the mouth of a river is complete.Finally around middle bag gas-permeable nozzle and brick cup, fill stamp mass, make it fixing, then remove this positioning guiding plate and use next time.
