法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for press-molding a refractory brick, and more particularly to a method for press-molding a refractory brick which can provide a dense and uniform molded body in the production of a refractory brick.
【０００２】[0002]
【従来の技術】耐火れんが製造業の成形工程では、乾式

得られにくく、坏土に加えた力をより均一に坏土内に伝
達することが望まれている。2. Description of the Related Art In a molding process of a refractory brick manufacturing industry, a dry molding machine is widely used because it can be mass-produced. However, it is difficult to obtain a completely uniform density with this molding machine, and it is desired to more uniformly transmit the force applied to the kneaded clay into the kneaded clay.

圧面圧１０００Kgf/cm2 以上の力での乾式方法で得られ
る成形体と比較すると、嵩密度が不足する。Therefore, as a method for obtaining a homogeneous molded body, C.I. I. A hydraulic press typified by P or the like, or a wet molding method or a casting method in which a large amount of liquid such as a binder is contained in a kneaded clay is used, but in any case, a pressing surface pressure of 1000 Kgf / cm is used. The bulk density is insufficient as compared with a molded product obtained by a dry method with a force of 2 or more.
【０００４】[0004]
【発明が解決しようとする課題】上記のように乾式成形
方法は、量産向きで、大型の成形機を用いて高圧でプレ
スできるので、高密度の成形体を得られる。As described above, the dry molding method is suitable for mass production and can be pressed at a high pressure using a large molding machine, so that a high-density molded body can be obtained.
【０００５】しかし、その反面、坏土中の粒子間に潤滑
剤となるバインダ−等の液体が少なく、粒子から粒子へ
作用、反作用の原理で力が伝達する間にせん断力等によ
り力の大部分が摩擦で発散される。On the other hand, on the other hand, there is little liquid such as a binder serving as a lubricant between particles in the kneaded clay, and a large amount of force is exerted due to shearing force, etc. while the force is transferred from particle to particle by the principle of reaction. Part is rubbed off.
【０００６】そのため、密閉した金型内であっても、圧
力が一様に伝わらないで、密度が不均一になる欠点があ
り、特に異形形状の耐火れんがの成形の場合に不均一な
状態が顕著に表れる。Therefore, even in a closed mold, the pressure is not evenly transmitted and the density becomes non-uniform, which is a non-uniform state especially in the case of molding irregularly shaped refractory bricks. Remarkably appears.
【０００７】一方、湿式成形方法では、坏土の粒子間に
十分の液体や潤滑剤があり、極端な場合はパスカルの静
圧原理が適用できる程度になる。On the other hand, in the wet molding method, there is sufficient liquid or lubricant between the particles of the kneaded clay, and in an extreme case, the Pascal static pressure principle can be applied.
【０００８】その結果、坏土の移動が容易で均一に力が
加えるため、均質で成形厚さ方向の寸法差がない成形体
ができる。As a result, the kneaded material can be easily moved and a uniform force is applied, so that a molded body which is homogeneous and has no dimensional difference in the molding thickness direction can be obtained.
【０００９】その反面、成形体に多くのバインダ−等の
液体を含むので、乾燥、焼成後に液体部分がなくなり、
嵩比重の低下、収縮、歪みによる亀裂等が発生する欠点
がある。On the other hand, since the molded body contains a large amount of liquid such as binder, the liquid portion disappears after drying and firing,
There is a defect that the bulk specific gravity decreases, shrinkage, cracks due to strain, and the like occur.
【００１０】したがって、乾式の成形方法と湿式の成形
方法の長所を取り入れた均一で高密度の成形体を量産で
きる方法が望まれていた。Therefore, there has been a demand for a method capable of mass-producing a uniform and high-density molded product, which takes advantage of the dry molding method and the wet molding method.

得られることを見出した。According to the present invention, since the horizontal force applied to the split mold is measured at each level of kneaded clay water because the split mold needs to be designed, when the moisture exceeds 6% by weight, the split mold gap is generated. It was found that water is discharged from the product, and as a result, a uniform molded product having a high bulk specific gravity can be obtained.
【００１２】特に、水分１０重量％付近では、プレスに
