Provided is a production method for high-carbon martensitic stainless steel in a strip-casting device, wherein a stainless-steel thin sheet is cast by supplying a stainless molten steel containing, as percentages by weight, 0.40 to 0.80% carbon and from 11 to 16% chromium to a molten steel pool from a tundish via a nozzle, and the cast stainless-steel thin sheet is made into a hot-rolled annealed strip using in-line rollers to a rolling reduction of 5 to 40% immediately just after the casting so that the size of primary carbides within the microstructure of the hot-rolled annealed strip is 10 μm or less, and also provided is martensitic stainless steel produced by means of the production method. By reducing the size of the primary carbides formed in the cast structure and the hot-rolled sheet to 10 μm or less, the present invention produces high-carbon martensitic stainless steel having outstanding blade-end quality for use in cutting implements.

摘要： An edge dam position control method and device in a twin roll strip casting process calculates the reduction ratio and rolling force of rolls to obtain the height of a solidification point, and adjusting the height of an edge dam during casting to correspond to the obtained height of the solidification point. It minimizes the force applied to the edge dam during casting, reduces the degree of wear of the edge dam, and improves the quality of edge portions of both sides of the strip. This new method includes the following steps: calculating the position of a solidification point to a rolling force of twin rolls and diagrammatizing the calculated result; measuring a real rolling force of the twin rolls upon casting by means of a load cell; determining whether the position of the solidification point to the measured rolling force of the twin rolls corresponds to the current height of the edge dam; and moving the edge dam to a position where the height of the edge dam corresponds to the position of the solidification point to the measured rolling force of the rolls.
