CLEVELAND (AP) _ LTV Steel Co. said Friday it would recall about 140 laid-off workers next week when it resumed operation of two electric furnaces in Cleveland.

But 1,300 other workers will remain idle at LTV's Cleveland Works, said company spokesman March Tomasch.

The recalled workers, who start work on Sunday, were laid off in April when the furnaces were shut down. The remaining 1,300 workers were laid off at the end of May because of decreased demand for its flat-rolled steel, most of which is used for auto bodies and parts.

''Inventory levels have declined over recent months, resulting in an increased need for steel,'' said W.G. Wiley, vice president of LTV Steel Flat Rolled and Bar Co., an operating unit of the Cleveland-based LTV Steel.

Steel produced by the electric furnaces will be processed by finishing facilities now operating at the Cleveland Works and other LTV plants.
