Patent number: 9744586Abstract: The binder coated refractories comprises the refractory aggregates and the solid-form coating layer which comprises the sugar group as the binder and which is provided to the surface of the refractory aggregates. According to this, the sugar group is used as the binder for bonding the refractory aggregates. Further, even if the sugar group is thermally decomposed, the sugar group emits the carbon dioxide and the water. Therefore, there is little likelihood of emitting the harmful gas. Therefore, it is possible to reduce the environmental pollution. Further, the sugar group is thermally decomposed easily. Therefore, it is possible to manufacture the casting mold having the good breaking property.Type: GrantFiled: May 22, 2015Date of Patent: August 29, 2017Assignee: LIGNYTE CO., LTD.Inventors: Isamu Ide, Toru Seki, Shinji Nishida

Patent number: 8082975Abstract: To provide a casting mold manufacturing apparatus using steam heating. The apparatus includes a forming die having a cavity, a resin-coated sand supply section for supplying a resin-coated sand into the cavity, a steam supply section for supplying steam into the cavity, and a steam discharge section for discharging the steam from the cavity. At least a portion of the forming die is composed of a porous material having pores with an average diameter smaller than an average particle diameter of the resin-coated sand. At least a portion of the steam is supplied into the cavity through the porous material. Since it is possible to uniformly supply the steam into the cavity, a homogeneous casting mold can be manufactured.Type: GrantFiled: April 27, 2007Date of Patent: December 27, 2011Assignee: Lignyte Co., Ltd.Inventors: Isamu Ide, Sadao Maeda

Patent number: 7784524Abstract: An apparatus and a method for producing a casting mold are provided, according to which the casting mold having a complex shape can be obtained with stable quality. The apparatus comprises a mold having a cavity therein, a steam supply unit, a steam supply passage connected to the cavity, steam discharge passages, flow regulators disposed in the steam discharge passages to regulate an amount of the steam discharged from the cavity, and a control unit for controlling the flow regulators. After a resin-coated sand prepared by coating a refractory aggregate with a binder resin is injected into the cavity of the heated mold, superheated steam is supplied into the cavity. At this time, the control unit controls the flow regulators such that the cavity is uniformly filled with the superheated steam.Type: GrantFiled: November 18, 2004Date of Patent: August 31, 2010Assignees: Lignyte Co., Ltd., Maeda Shell Service Co., Ltd.Inventors: Isamu Ide, Toru Seki, Sadao Maeda, Keizo Nishiyama
