With the development of the machinery industry, the molten iron ladle is valued and welcomed by the leaders and workers of the mass enterprises. According to the constraints of resources, energy, environment and other factors, iron and steel enterprises should not only undertake the manufacturing function of steel products, but also undertake the energy conversion and the treatment and removal of some bulk waste in society. In particular, the energy consumption of the new steel plant should be less, the land occupation should be less, and the environment should be protected. According to the requirements of modern steel production technology, the retreating of blast furnace must be pretreated completely or partially before entering the whole road

The ladle is an essential production equipment for casting production, especially in the production of nodular cast iron, the ladle structure plays an important role. In order to ensure safety and retreat the debris formed by spheroidization reaction and secondary reaction in the ladle, many domestic and foreign foundry enterprises or foundry equipment enterprises are constantly exploring a good cast iron price house< br/>
? In addition, the casting equipment enterprises only manufacture the hardware workshop shell, and there is no specific standard for the hardware packaging. The casting production unit should design according to the actual situation

The hardware workshop refers to the connection - matching, adjustment - buffering technology and corresponding devices (equipment) between the steel and the main process of steelmaking, and then the slag is stripped off and replaced with a dephosphorization electric furnace for dephosphorization, then poured into the iron bag, and finally entered into the decarburization heating electric furnace for smelting (rapid decarburization, rapid heating). This mode has better desulfurization thermodynamic conditions, can be added with heat preservation, fast time rhythm and low temperature

The molten iron ladle is the volume of the molten iron room calculated by the capacity of the molten iron room in the reduction furnace workshop, which can be calculated according to the following formula: V1 - volume, m3. K - iron unbalance coefficient, 1.2; P - daily output of electric furnace, t/d; N - number and time of iron occurrence in the evening; 1 - density of molten iron, t/m3; M1 - total coefficient of hot metal packaging, 0.85~0.9 for slag-free method and 0.7~0.75 for slag-free method. There are many types of withdrawal packages, and their main technical parameters are shown in Table 5-26~5-28. The cast steel hardware bag without lining is hung with residue before use. Compared with the hardware bag with lining, it saves labor for refractory bricks and masonry

The withdrawal package is used for casting work in the casting workshop. After receiving the molten iron in front of the furnace, it is transported from the driver to the mold for casting


1. Hanging packaging, two-way rotation. 2. Gearbox type, double worm gear pair drive< br/>
