摘要： PURPOSE:To improve sealing performance and simplify handling by arranging a plurality of outlet pipes onto a rack along the locus drawn by an elevation pipe through the turn of a connecting pipe, permitting the connection with the elevation pipe. CONSTITUTION:Three outlet pipes 41-43 are arranged at the fan-shaped part 3 of a rack along the locus drawn by an elevation pipe 35 through the turn of a connecting pipe 7, permitting the connection with the elevation pipe 35. When the elevation pipe 35 is raised by driving a motor 38 until a valve piece 25 contacts with a valve seat 12, the fluid on the upstream side is cut-off at the outlet 11 of the connecting pipe 7. When, the connecting pipe 7 is turned by driving a motor 29, and the elevation pipe 35 is lowered by driving the motor 38 until the undersurface of the elevation pipe 35 contacts with the gaskets 47 of the outlet pipes 41-43, fluid flows into the outlet pipes 41-43 from the gap formed between the valve piece 25 and the valve seat 12.

摘要： PURPOSE:To obtain a hot-dip galvanized sheet of high tensile strength steel with high Si content free from uncoating, excellent in uniform external appearance, and having superior adhesive strength of plating by modifying the thickness of an oxide film by adopting a control system on a continuous line and providing an oxide film thickness gage for satisfying specific conditions. CONSTITUTION:A strip 1 of high tensile strength steel having >=0.3% Si concentration in steel is preheated and is then heated up to about 700 deg.C in a direct-fire heating furnace 3, and the thickness of the iron oxide film formed is observed and the resulting observed value is sent to a desired oxide film comparing and computing machine. On the other hand, in the above computing machine, iron oxide film reducing capacity in a reducing zone is computed by using heat cycle, line speed, and hydrogen concentration in the reducing zone. The observed value from the film thickness gage 6 is compared with the desired value set from inequalities on the basis of the observed oxide film thickness in the oxidation zone and feedback control is done to the direct-fire heating furnace 3 by means of the resulting difference signal, by which oxide film thickness can be modified.

CONSTITUTION:At the time of annealing a high tensile strength steel sheet having >=0.3% Si concentration in steel, the thickness of an iron oxide film formed in an oxidation zone in an annealing furnace is measured by means of an oxide film thickness gage and also iron oxide film reducing capacity in a reducing zone is computed by using heat cycle, line speed, hydrogen concentration in a reducing zone, and combustion air ratio in an oxidation zone, and annealing conditions are controlled so that inequalities I, II are satisfied. In the above inequalities, (a) means allowance of oxide film and (b) is a constant determined by Si content in steel. Subsequently, the steel sheet is passed through a molten zinc bath. Further, it is desirable that heating in the oxidation zone is exerted by using a burner throwing a flame perpendicularly to the steel sheet.
