目前,高炉朝着大容积、高顶压、高风温的强化冶炼方面发展,而且无水炮泥等坚硬的堵铁口用泥料应用越来越广泛。因此,对炉前堵铁口机械——泥炮也就提出了新的要求,即:结构简单,制造、维修方便;打泥能力强;炮柱低矮,便于机械换风口作业。我国各类高炉现在采用的泥炮大部分仍是电动泥炮,它们不足之处表现为: At present, the blast furnace towards large-volume, high top pressure, high temperature of the strengthening of the development of smelting, but also non-dry stems and other hard blocking the use of clay material more widely used. Therefore, the front of the furnace blocking iron machinery - mud will also put forward new requirements, namely: simple structure, easy manufacture and maintenance; mud hit ability; low column, easy mechanical ventilation outlet operation. Most of the mud guns now used in various types of blast furnaces in our country are still mostly electric mud guns. Their inadequacies are as follows:
