The aluminum-aluminum industrial tap out cone produced by our “Adtech Jiaozuo Metallurgical Materials Co., Ltd.” is made of aluminum silicate refractory fiber spun silk cotton and quantitative binder through a special mold and vacuum suction filtration. The product has a certain strength. It is suitable for heat preservation and sealing of outlets of aluminum, copper, zinc smelting furnaces, refining furnaces, static furnaces, etc., making the casting process of aluminum, copper, and zinc alloys more convenient, safer, and more reliable.
Product advantages of Ivans aluminum industrial insulation hat:
1. Vacuum suction molding of high-alumina fiber, non-stick aluminum, and no slag;
2. Uniform distribution of plastids, good elasticity, tight plugging, and stable flow control;
3. High hardness, long service life;
What is the joint of the thermal tap out cone and in what areas can it be applied:
The junction of the insulation cap is a metallurgical term; it is used for the ingot casting equipment used to insulate the aluminum water at the head of the calming aluminum ingot; The volume shrinkage of the molten aluminum in the ingot body is continuously replenished during the solidification process, so that the final shrinkage cavity is located above the cap line, ensuring that the ingot body structure is dense and does not appear shrinkage cavity and looseness, so as to reduce the defects of the aluminum ingot and the loss of the billet cutting head Purpose. The thermal insulation cap is generally composed of a cast iron shell and a refractory lining; the type of thermal insulation cap can be divided into two types: fixed type and floating type according to the placement method; the former is suitable for rolling aluminum ingots, and the thermal insulation caps are placed smoothly on the aluminum ingot mold The latter is suitable for forging aluminum ingots. By adjusting the height of the pillar under the trunnion of the tap out cone, pouring aluminum ingots of different weights can achieve a multi-purpose mold. At the same time, after the injection is completed, the support is removed, and the thermal insulation cap can freely fall with the condensation and shrinkage of the aluminum ingot so that the aluminum ingot does not cause transverse cracks due to suspension. According to the properties of lining refractory materials, there are clay bricks, lightweight clay bricks, cinder bricks, and insulation boards. Insulation panels for the 1970s
Due to the small heat capacity and extremely low thermal conductivity of the developed and applied new hat opening insulation material, the ratio of the volume of the hat to the total volume of the aluminum ingot (that is, the cap volume ratio) can be changed from about 16% to 20% of that of the traditional clay brick insulation hat. , reduced to about 10% to 14%; when pouring killed aluminum with an upper small lower large open aluminum ingot mold, hang or inlay the heat insulating plate on the inner wall of the upper mouth of the aluminum ingot mold at a certain height; use the traditional upper large When pouring killed aluminum in the lower small aluminum ingot mold, the heat insulation board is directly embedded in the iron shell of the tap cone, and some are directly embedded in the inner wall of the upper opening of the aluminum ingot mold. At this time, because the height of the cap mouth is significantly reduced, it is necessary to design an aluminum ingot mold with a gap to ensure that the clamps of the demoulding crane can clamp the head of the aluminum ingot and de-mold smoothly;
