It enables long-term management of green sand, improvement of cast surface and quality by better collapsibility of high quality coal with high coat ability on sand. 1.Improvement of cast surface and prevention of seizure 2.Suppression of pinhole defects by FCD 3. Improvement of collapsibility Improvement of cast surface and prevention of seizure ■ Reducing Atmosphere Theory Because volatile matter of carbon mainly consist of reducing substances such as hydrogen etc. the interface between hot metal and mould is so reducible that the generation of iron oxide is suppressed and the generation Fe+O→FeO 2FeO+SiO2→2FeO・SiO2 of iron silicate prevents the cast surface defects and seizure. Fe+O→FeO 2FeO+SiO2→2FeO・SiO2 ■ Gaseous Cushion Theory Volatile matter content in the coal powder is gasified by the heat of molten metal so that a gas film is built up, which prevents the direct contact of the molten metal and mould surface, hence improves the cast surface and prevents the seizure. ■ Lustrous Carbon Theory Volatile matter content in the coal powder undergoes thermal decomposition on the hot mould interface and forms carbon film on it, which prevents direct contact of the hot metal and mould, so that the cast surface is improved and the seizure is prevented.

OS Pax is a high-silica refractory OS Pax belongs to plastic refractories and is adjusted to adequate softness by adding water. OS Pax has superior corrosion resistance by dosage of graphite SiO and is a refractory with its wide usability. ■ Features of OS Pax High heat resistance High purity raw material is utilized as aggregate and has wide usability, and by means of dosage of minute mineralizer a good densification and high heat resistance in a high temperature range (1200~1500℃)are achieved. High corrosion resistance with dosage of SiC and graphite a superior feature, such as high resistance to abrasion by molten metal and slug, is given. ■ Chemical Components

For the purpose of molten metal treatment a lot of slag removal agents such as pumices、pearlite etc. ■ Features of Connector Compared to pumices and pearlite, consumption saving of 30% can be achieved. Oxygen in the atmosphere is shut off, so that the temperature reduction is prevented. Less adhesion to electro furnace and ladle. No substances are contained, which could deteriorate molten metal. ■ Component Value
■ Varieties Exclusively for electro furnace ・・・・ Connector (J) For both ladle and electro furnace ・・・・ Connector (S) ■ Sizes less than 0.2㎜~3㎜ less than 0.2㎜~1㎜ less than 1㎜~3㎜ ■ Utilization 1. In case of slag removal, scatter thin and uniformly. When heat retention, scatter around 10mm thick on the whole area, then the contact surface with molten metal is molten to ■ Product Package 25kg Paper Bag 1t Flexible Container Pack |

Graphite Patch is a patching material for light repair of ladle, forehearth, drainpipe, hand shank etc., has high heat-retaining property because of heat resistant silica as main component and allows extraordinary high fire-resistant property being used in combination with OS Pax. This is, similar to the OS Pax, a high siliceous refractory. Because of finer particle size, adequate refractory for rationalizing workmanship management. ■ Features of Graphite Patch 1.Low water content makes workmanship management easier. 2.It shows excellent By adding SiC and graphite it shows excellent feature of high abrasive resistance ■ Component Value
