Abstract
The invention provides a quenching method for deformed steel bars. The method comprises the following steps: after heating the deformed steel bars to 960-980 DEG C, preserving the heat for 1-2 h; and immerging into a quenching agent for quenching, wherein the quenching time is 3-5 s, and the quenching agent is composed of the following components by mass: 5-7% of industrial sodium chloride, 1-2% of sodium nitrate, 1-2% of potassium sulfate, and the rest of distilled water. Through the application of the quenching method for deformed steel bars to quench, the obtained deformed steel bars have excellent rust-proof performance, the performance of an oxide skin is improved, and the quenching method is simple and convenient to use.
Description
Technical field
The invention belongs to the heat treatment technics field, be specifically related to a kind of quenching method of Deformed Steel Bars.
Background technology
Deformed Steel Bars belongs to the small section steel, generally is widely used in the civil engineering construction such as house, bridge, road, mainly as the skeleton of reinforced concrete building member.The purposes of Deformed Steel Bars is bearing tension in concrete member, concavo-convex different thread surface can with the better combination of concrete, can prevent that frictional force between invar muscle and concrete is not enough and mutually break away from, cause the situation of structure deteriorate to occur.
Deformed Steel Bars easy rust corrosion in medium around carbonic acid gas, oxygen, water, the acid etc. in storage, transportation and use procedure.Corrosion not only causes the waste of steel, affect the outward appearance of Deformed Steel Bars, and reduced reinforcing bar intensity and and concrete between bonding force, caused the potential safety hazard of producing and living.Take effective measures the corrosion that slows down Deformed Steel Bars particularly important.
The at present actual employing of the quenching heat treatment of Deformed Steel Bars be generally Direct Air-Cooled or wear water cooling after hot rolling.Yet, if adopt air cooling, mechanical property will not reach requirement; If the employing water-cooled, its surface scale can be transformed into iron rust very soon, affects performance and the use of Deformed Steel Bars, and this is a great problem that perplexs for a long time the Deformed Steel Bars application.
