設している。[Prior Art] Conventionally, in the molding of refractory bricks having recesses on the sides, clay was placed in a metal frame, and the clay was pressurized, compressed, and shaped from above using hydraulic pressure, friction, etc. Finally, the molded body is pushed upward into the metal frame using hydraulic pressure from below to obtain a molded body, and after this molded body is fired, a recessed hole is bored in the side surface using a drill.

【発明が解決しようとする課題】かかる従来の凹部の形
成は、坏土の成形とは別工程で行っているために、作業
効率が悪く、製品コストを上げている。[Problems to be Solved by the Invention] Since the formation of such conventional recesses is performed in a separate process from the molding of the clay, the work efficiency is poor and the product cost is increased.

うな耐火れんがの側面の凹部の形成を坏土の成形時に行
うための手段を見出すことにある。[0004] The problem to be solved by the present invention is to find a means for forming such a recess on the side surface of a refractory brick at the time of molding the clay.

体中に耐火物原料を充填加圧することを特徴とする。[Means for Solving the Problems] The present invention involves adhering a magnetic material having a shape and size corresponding to a recess to be formed in advance to a predetermined position on the inner surface of a molding frame made of a ferromagnetic material, and It is characterized by filling a refractory material inside and pressurizing it.
【0006】[0006]

を成形と同時に形成することができる。[Operation] The arrangement position of the molding magnetic material magnetically attached to the inner surface of the molding frame shifts in the pressing direction during pressure molding of the clay. By predicting this deviation empirically and pasting the adhesive at a position that takes into account the deviation, it is possible to form a side recess at a substantially planned location at the same time as the molding.

よりも所定の上方位置に磁力によって貼着している。In the figure, 2 is a mold body made of iron, and 3 is a bottom plate disposed on the inner bottom surface of the form, and the center of the bottom plate 3 has a hole for forming an inner hole surface. Core 4 is attached. Reference numeral 5 indicates a recess forming member for forming a recess into which a gas introduction pipe is attached on the side surface of the manufactured porous refractory brick. The recess forming member 5 is made of ferromagnetic material, and the recess 6 for attaching the gas introduction pipe to be finally formed.
It is attached to a predetermined upper position by magnetic force.

取り出す。When the filled clay 7 is molded by pushing the upper frame 8, the recess forming member 5 is moved from the pre-arranged position shown by the dotted line to the planned gas introduction pipe attachment due to the flow accompanying the pressurization of the clay 7. The molded body 9 slides into position and a recess is formed there, and the molded body 9 pushes up the bottom plate 3 in the direction of the arrow to take out the molded body.
