For this reason, hot metal pretreatment technologies such as hot metal dephosphorization, desulfurization, and pre-desiliconization for dephosphorization have rapidly developed. Among them, the pretreatment method using a hot metal wheel makes it possible to use an existing hot metal wheel as a reaction vessel. Widely adopted by

る。As shown in FIG. 5, the pretreatment method for a hot metal pig is a process for removing silicon by using an inert gas such as nitrogen gas as a carrier gas from an upper pig iron inlet 26 of a furnace body 25 of the hot metal via a refractory lance 27. It is carried out by blowing an agent, a dephosphorizing agent, and a desulfurizing agent into the hot metal 28 according to the purpose of treatment. In some cases, temperature control of the hot metal 28 or oxygen supply by an oxygen lance 29 as an oxygen source is often performed at the same time. Splash of hot metal 28 and slag, or generation of slag (forming) is intense at the time of injecting these agents and supplying oxygen, and these attach to the portion of the upper pigtail port 26 or from the pigeon port 26 to the furnace of the mixed piggy car. Since it scatters to the outside, a splash prevention cover 30 is provided on the gun mouth 26 as a preventive measure.

As shown in FIG. 6 to FIG. 7, since the irregular shaped refractory 32 such as high alumina is attached to the inside of the iron shell 31 having a funnel-shaped longitudinal section, the irregular shaped refractory Object 32
However, due to the effects of radiant heat from the hot metal 28, erosion due to the scattered hot metal and slag, and erosion due to the high temperature gas flow due to oxygen supply, the actual situation is that the wear and wear disappears in a very short period of time, and the durability is reduced. Lack. Moreover, replacement of a worn cover requires a great deal of work, and in addition, the pretreatment must be stopped during the replacement period. And it has a significant cost penalty.

である。On the other hand, the applicant has previously made a splash prevention cover for desulfurization treatment (design registration No. 1), in which the cover body is made of cast iron in place of the conventional irregular shaped refractory and a refrigerant passage is formed inside.
569444: See Japanese Patent Application No. 54-28866). By the way, since this splash prevention cover is made of cast iron, it is expensive and is sufficiently applicable to desulfurization performed at a relatively low temperature, but it is often used in combination with desiliconization and oxygen supply. When applied to phosphorus, the scattered hot metal adhering to the splash prevention cover is the CO generated by oxygen supply.
Alternatively, it is difficult because the temperature is melted (about 1500 ° C.) by CO 2 gas, and the cast iron having a low melting point is melted by this heat and melted over time, which is difficult.

Therefore, by passing cooling water through this metal pipe, it is possible to suppress the temperature rise of the inner surface of the cover due to the high temperature gas flow due to the radiant heat from the hot metal or the supply of oxygen, and the scattered hot metal and slag are scattered on the inner surface of the cover. Even if it adheres, it instantly solidifies and spontaneously falls, or peeling and removal are facilitated, so that the inner surface of the cover is less likely to be eroded and the durability can be improved.

In this case, the scattered hot metal and slag can be prevented from directly adhering to the metal pipe, and the durability of the metal pipe is improved. At the same time, the refractory is cooled by the metal pipe. The slag is rapidly cooled to reduce adhesion and improve the durability of refractory materials.
