摘要： PURPOSE:To prevent the dilution of a high-density rolling mill lubricant by roll cooling water and to prevent the degradation of lubricity by disposing nozzles for injecting the high-concn. rolling mill lubricant to the inlet side of a rolling mill and disposing jacket type coolers oppositely to the outer peripheral faces of rolling rolls to the outlet side of the rolling mill. CONSTITUTION:The pressurized cooling water sent to a water feed pipe 15 passes a pipe body 12 and is sent to a water feed header 20 and is further projected from slit nozzles 20a of the water feed header 20 so as to be forcibly passed in cooling water passages 19. This water enters the inside of a drain header 21 from a drain port 21a and is drained through a pipe body 13 and a drain pipe 16. The cooling water of the roll 2a is supplied while the water forms a water film with the outside peripheral face of the roll 2a in the hermetically sealed jacket type roll cooler 5 and, therefore, the roll cooling power is extremely high and the leakage of the cooling water from sealing parts 6a, 6b is obviated. The dilution of the high-concn. rolling mill lubricant by the cooling water is prevented.

摘要： PURPOSE:To economically float and support a metal strip and to reduce variation of pressure in a furnace by raising the temp. after raising the pressure of low temp. gas, passing it through an ejector and sucking the high temp. gas in the furnace, raising the pressure and injecting both gases to the lower face of the metal strip from a wind box. CONSTITUTION:After raising the pressure of low temp. gas in the furnace or from outside of the furnace by compressor 37, the temp. is raised by a temp. raising device 33. The high temp. and high pressure gas obtd. by this method is passed through the ejector 21 as driving gas. This driving gas is injected from the nozzle part 26 of the ejector 21, to generate the negative pressure to a throat 27. By this negative pressure, the high temp. gas in the continuous annealing furnace 11 is sucked through sucking flowing path 29. The pressure of this sucked high temp. gas is raised by the ejector 21 and this gas is injected to the lower face of the metal strip 13 running in the above high temp. furnace 11 from the wind box 15 together with the above driving gas. By this method, the floating of the above metal strip 13 is supported without using an expen sive circulating fan for high temp. under controlling the variation of the pressure in the furnace.

摘要： PURPOSE:To avoid loss of effect caused through high temperature hysteresis such as strain relief anneal by a method wherein a grain oriented silicon steel plate which is finished to have mirror surface is rolled into a loose coil in which the plate surfaces are separated from each other and subjected to a depressurized CVD process to form a very thin tension film on the steel plate surface. CONSTITUTION:A grain oriented silicon steel plate is rolled into a loose coil 9 and the coil 9 is inserted into a vacuum furnace 1 and the vacuum rate in the furnace is made to be 10 -10 Torr by the operation of a vacuum pump through a vacuum passage 8. After that, while H2 gas is being introduced through a gas introduction passage 4, in order to improve circulation of the gas in the furnace, the gas is extracted through a gas exhaust passage 10 and the inside of the furnace is always under the depressurized condition (normal operating pressure is 1-500 Torr) and the gas flow through the gaps between the steel plates of the loose coil 9 is kept smooth. Then, after a heater 3 is operated and the coil temperature reaches 600 deg.C-1,000 deg.C and kept at that, a mixture gas such as TiCl4 and N2, TiCl4 and CH4 or TiCl4 and CH4 and N2 is introduced through the gas introduction passage 4 and a very thin tension film is formed on the steel plate surface by a depressurized CVD method in 5min-100hr.
