摘要： PURPOSE:To restrain the production of nitride by forming surface layer of molten metal contact part in a brake ring for horizontal continuous casting composed of the nitride with oxide layer excluding the nitride. CONSTITUTION:The brake ring for jointing a tundish and a mold for horizontal continuous casting is constituted so as to be composed of mainly the nitride and the oxide layer excluding the nitride with oxidizing treatment at the surface layer part on the molten metal contact part. By this method, this brake ring has excellent high temp. strength, heat shock resistance, machinability, etc., but the production of nitride into the molten metal is remarkably restrained, and the surface defect of a cast billet and the segregation of the nitride can be drastically restrained.

摘要： PURPOSE:To reduce erosion of a refractory, by forming gas penetrating restrained layer for restraining penetration of gas on surface layer in contact with outer air. CONSTITUTION:With the connecting refractory 1 for continuous casting, a mold for continuous casting and a tundish are connected. Then, at least on the surface layer part in contact with the outer air, in the refractory 1, coating layer 4 as the gas penetrating restraining layer for restraining the penetration of gas, is formed. The coating layer 4 is formed with e.g. borosilicate glass series glaze. By impregnating chromium oxide in pores on surface layer of the refractory, the gas penetrating restraining layer is formed. By this method, it can be restrained that glass phase is developed by oxidizing the nitride as a part of the composition.

摘要： PROBLEM TO BE SOLVED: To provide a square tube which can be used for an electronic component, and is excellent in the dimensional accuracy.
SOLUTION: The subject method is for manufacturing a square tube, in which a round tube comprising a kovar alloy is drawn to a rough square tube by cold drawing, and then finished to the square tube by cold drawing. The thickness of corner parts in the rough square tube obtained from the round tube is thinner than that in the round tube. After applying heat treatment to the rough square tube to relieve the stress, drawing work is applied thereto to make the thickness of the corner parts in the finished square tube thinner than that in the rough square tube, and to make the difference among short side part Rd (cross-sectional area reduction rate: %), long side part Rd (cross-sectional area reduction rate: %), and corner part Rd (cross-sectional area reduction rate: %) 2% or less. When at least one drawing work is applied to the rough square tube, it is necessary that, after applying heat treatment to the rough square tube obtained right before to relief the stress, the rough square tube having thinner corner parts than the rough square tube is drawn.

The portion to be bent is previously subjected to thickness deviation working in such a manner that the ratio of the wall thickness of the portion to be the back side of the curved pipe/the wall thickness of the curved pipe to be the ventral side of the curved pipe is ≥1.2. The working method performs high frequency bending by using the steel pipe and regulating the bending radius to (1.5 to 2.0) x (the external diameter of the pipe). The occurrence of the microcracks during working can be prevented. COPYRIGHT: (C)2010,JPO&INPIT
