Abstract
The invention relates to a continuous casting method for easily drawable steel wires, which is characterized in that: steel SAE1006 and SAE1008 are cast continuously in turn, namely the SAE1008 steel is cast after the SAE1006 steel is casted; the components of the SAE1008 steel which is continuously cast with the SAE1006 steel in a steel mixing area are controlled; and thus, the components of the molten steel continuously cast in the steel mixing area meet the requirements on the components of SAE1006. The method has the advantage that the components of the molten steel continuously cast with the SAE1006 in the steel mixing area meet the requirements on the component of the SAE1006, so that the utilization value of the steel blank is maximized.
Description
Technical field
Continuous cast method waters in the company that the present invention relates to a kind of easy wire drawing steel, belongs to the steel-making continuous casting field that metallurgical industry is produced.
Background technology
Baogang receives a user's order, only needs 2 stove SAE1006 steel (steel about 200t altogether).In order not lose the user, this steel grade of decision exploitation.If but one of continuous casting waters and time only produces 2 stoves and can cause bigger waste and production cost also higher (about 30,000 yuan of the expense of watering is unwrapped in a centre in the continuous casting production; With the tundish of little square billet coupling generally at least can continuous pouring 35 stove steel); Therefore must the selection component steel grade close connect with it and water with the SAE1006 steel, and can make the satisfied wherein a kind of steel of molten steel composition that mixes steel district (two Mixed Zones of steel grade in tundish) chemical composition so that the steel billet value maximize.
Summary of the invention
The objective of the invention is to the SAE1006 steel and can not satisfy a company when watering needed stove and counting, need connect and water and the value of steel billet is maximized, provide a kind of company of easy wire drawing steel to water continuous cast method with other steel grade.
Method of the present invention is following:
SAE1006 steel and SAE1008 steel connected water; Even watering order is to water the SAE1006 steel earlier; Connect after the SAE1006 steel has watered and water the SAE1008 steel, and the composition that connects the SAE1008 steel that waters with the SAE1006 steel that mixes the steel zone is carried out control corresponding, control will be asked for an interview to table 3.
The composition requirement of table 1 SAE1006 steel, w%
| Steel grade | C | Si | Mn | P | S |
| SAE1006 | ≤0.08 | ≤0.15 | 0.25-0.45 | ≤0.035 | ≤0.035 |
The composition requirement of table 2 SAE1008 steel, w%
| Steel grade | ?C | Si | Mn | P | S |
| SAE1008 | ?＜0.1 | ≤0.10 | 0.30-0.50 | ≤0.035 | ≤0.035 |
Table 3 connects the SAE1008 composition of steel requirement of watering, w% with the SAE1006 steel
| Steel grade | C | Si | Mn | P | S |
| SAE1008 | ≤0.08 | ≤0.10 | 0.25-0.45 | ≤0.035 | ≤0.035 |
All the other are iron and unavoidable impurities.
Advantage of the present invention is: solved the SAE1006 steel and can not satisfy a company when watering needed stove and counting, made the molten steel composition that connects in the mixed steel district of watering with the SAE1006 steel meet the requirement of SAE1006 composition of steel simultaneously again, thereby realized the maximization of steel billet value.
The specific embodiment
Can develop smoothly for the steel grade that guarantees trial-production, 2 stove SAE1006 steel are placed on the 1st stove and the 2nd stove that even waters, the 3rd stove is for connecting the SAE1008 steel that waters with it, and the actual constituent control of this 3 stove steel is as shown in table 4.SAE1006 (1) refers to the first stove SAE1006 steel produced.
The SAE1006 steel of table 4 actual production reaches and connects the SAE1008 composition of steel control situation of watering, w% with it
| Steel grade | C | Si | Mn | P | S |
| SAE1006(1) | 0.07 | 0.11 | 0.32 | 0.027 | 0.021 |
| SAE1006(2) | 0.06 | 0.12 | 0.41 | 0.029 | 0.018 |
| SAE1008 | 0.07 | 0.08 | 0.37 | 0.024 | 0.022 |
To the steel billet sampling that mixes steel district various flows (this conticaster has 8 streams) and carry out chemical composition analysis (mainly analyzing C, Si, Mn element), the result is as shown in table 5.
Table 5 mixes the main chemical compositions analysis of steel district steel billet, w%
| Mix steel district sampling point | C | Si | Mn |
| The 1st stream | 0.06 | 0.11 | 0.38 |
| The 2nd stream | 0.06 | 0.10 | 0.38 |
| The 3rd stream | 0.07 | 0.10 | 0.39 |
| The 4th stream | 0.06 | 0.11 | 0.39 |
| The 5th stream | 0.07 | 0.10 | 0.39 |
| The 6th stream | 0.07 | 0.10 | 0.40 |
| The 7th stream | 0.06 | 0.09 | 0.39 |
| The 8th stream | 0.07 | 0.10 | 0.40 |
Visible by table 5, the chemical composition of mixing steel district strand all satisfies the customer requirements of SAE1006 steel, therefore it is all issued wire rolling plants and is rolled by finished product, and the mechanical property of steel is as shown in table 6.
The mechanical property testing result of table 6 transition region steel
| Tensile strength, MPa | Percentage elongation, % | |
| The transition region steel mechanics performance | ?355 | 34.5 |
| Customer requirements | ?≤390MPa | A≥30％ |
Visible by table 6, the mechanical property of transition region steel satisfies user's requirement fully.
