摘要： PROBLEM TO BE SOLVED: To provide granular inorganic fiber cotton which has a bulk density suitable for a blowing method requiring lightening, and is carriable under compressive packaging, and whose bulk density can be restored to the lightweight one for use, and to provide a method for producing granular inorganic fiber cotton. SOLUTION: A melted inorganic matter is made into fiber, and the fiber is collected in a cotton state and granulated. In this case, while the remaining heat of the inorganic fiber drops to an ordinary temperature, a resin emulsion forming a resin film having the lowest film production temperature of =10 deg.C is stuck in an amount of >1 mass% expressed in terms of an emulsion solid content to the inorganic resin to produce the granular inorganic fiber cotton. The granular inorganic fiber cotton has a bulk density of , and the bulk density is restored to the original one when the cotton is released from a temporarily compressed state.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of rock wool which can recover the fiber excellent in quality without converting a existing facility and removing work of a shot. SOLUTION: The manufacturing method of the rock wool is that a molten material of contents adjusted blast furnace slag which is used as a main material is poured on a side surface of a cylinder body revolving with high speed with a horizontal axis, and by jetting air along the side surface in parallel direction to the axis, the molten material is scattered with centrifugal force and the air and is formed into a linear body, surface temperature of the molten material is measured on the side surface of the cylinder body, and the temperature of the molten material poured on the side surface is controlled so that the measured value is kept in the temperature range which is set previously.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of rock wool by which thinning a fiber diameter and restraining generation of a part of non-fibered are accomplished at the same time without converting the existing device, and not only a light board excellent in heat insulating characteristics but also a board having different heat insulating characteristics corresponding to use cane be made distinctively. SOLUTION: The manufacturing method of the rock wool is that a molten material of contents adjusted blast furnace slag is poured on a side face of a cylinder body revolving with high speed with a horizontal axis, and by jetting air along the side surface in parallel direction to the axis, the molten material is fly off with centrifugal force and the air and formed into a linear body. According to a thermal conductivity of the manufacturing rock wool, a relation between SiO2 concentration of the molten material and temperature of the molten material on the surface of the cylinder body is set, and operation is done according to the relation.

摘要： A method of producing a grain oriented silicon steel sheet is adapted to lower the iron loss. A silicon steel slab, containing about 2.0 to 4.0 weight % of Si and an inhibitor-forming amount of S, or Se, or both, is hot rolled. After the hot rolled steel sheet is annealed when necessary, the steel sheet is cold rolled into a cold rolled steel sheet having a final thickness by performing cold rolling either one time or a plurality of times with intermediate annealing therebetween, the cold rolled steel sheet then being subjected to decarburization, coating of the surface of the steel sheet with an annealing separation agent mainly comprising MgO, secondary recrystallization annealing, and purification annealing. In the cold rolling step, an oxide layer exists on the surface of the steel sheet. Specifically, in the cold rolling step, rolling oil is supplied only at the entrance of the rolling mill used, and an oxide layer having a thickness of about 0.05 to 5 mu m is generated. Or, an outer oxide layer of an oxide layer structure generated on the surface of the steel sheet after hot rolling or intermediate annealing, is removed, and an inner oxide layer of a thickness of about 0.05 to 5 mu m is maintained on the surface, the resultant steel sheet then being subjected to cold rolling.
