Short answer - you cannot - cast &/or convert will return an error if the value fails to convert to an integer.
Long answer - the below will work;

SQL

-- Declare a Table variable
DECLARE @MyTableVariable TABLE
(ErrorNumber INT)
-- Populate your Table variable
INSERT INTO @MyTableVariable
SELECT CAST(ErrorNumber AS INT) AS ErrorNumber
FROM MyTable
WHERE ISNUMERIC(ErrorNumber) = 1
-- Query the Table Variable
SELECT ErrorNumber 
FROM @MyTableVariable
WHERE ErrorNumber BETWEEN 355 AND 564

Kind Regards

CREATE TABLE #temp(mixedvalues VARCHAR(10));  
INSERT INTO #temp
      VALUES('T863'),
            ('356'),
            ('F5963'),
            ('563'),
            ('3659'),
            ('340T');


;WITH CTE AS(
   SELECT SUBSTRING(mixedvalues, 
            PATINDEX('%[0-9]%', mixedvalues),
               (LEN(mixedvalues)-PATINDEX('%[0-9]%',REVERSE(mixedvalues))+1)) AS 
                  NumericValues FROM #TEMP)
   SELECT * FROM CTE WHERE NumericValues between 355 and 1000;
